Abstract

The present invention relates to a filamentous phage display method wherein the polypeptides of interest displayed on the phage particle are cotranslationally translocated across the cytoplasmic membrane of Gram-negative bacteria based on the signal recognition particle pathway. This method is particularly suitable for polypeptides, which are known to be difficult to display on phages, and for proteins of cDNA libraries and other combinatorial libraries, in particular when derived from very fast folding, stable protein scaffolds. The invention further relates to phage or phagemid vectors useful in the method comprising a gene construct coding for a fusion polypeptide comprising the polypeptide to be displayed on the phage particle and an N-terminal signal sequence promoting cotranslational translocation.
